I received a (rescue hen) that was poorly taken care of. She has/had scaly leg mites and lice really bad which I have been treating. It's been a week a have applied Vaseline to her feet twice and permethrin powder (I believe) to her feathers for the lice, also 4 drops of Ivermectin for the leg mites (once). She has never been in contact with my flock and is staying in her own rabbit hutch until better. I allow her to free range but not where my other hens are or can go. My main question is will I ever be able to integrate her with my flock without chance of spreading leg mites to them?
